Originally posted by BIMMIN As far as I know you have a bad groud connection, try running it some where else. Anywhere on the frame or something like the bolt the seat belt is bolted to. Make sure it's bare metal.

It's not a bad ground. The first culprit is most likely your line converters...what brand did you use? The second, and MOST COMMON, is your RCA cables, you probably need MUCH better ones. The third, your speaker wire going to the front speakers, is it twisted wire, or did you just tap the factory wires?

are your RCA's running where the power wire is, since the battery is in the trunk there is a power wire connected to your alternator (passenger side)and if the RCA's are too close you will get alt. noise, try running your RCA's along the drivers side of the car. if that doesn't help Try noise filters, they really do work

get the real good noise filter. i still think noise filter helps a lot, but it is completely stopping it. even the shop cannot filter out all the noise for me. it's ignoring when the music is low volume. i have never tried out the line driver or converter. i will see about it.

I was really worried that I would have that kind of problem, so I told my audio installer to run my RCA cables right through the center of the car. That means running the wires under the area of the e-brake. Doing this will require way more labor than running the cable on the sides because you will have to strip many of the interior components. However, I went that way and I don't have problem with noise at all. Good luck
